Such detailed pictures of the cells, blood vessels and nerves at the back of the eye could enable earlier diagnosis and better treatment for degenerative eye and neurological diseases.http://phys.org/news/2015-06-technology-eye-cells-focus.html
Optics & Photonics Tue, 23 Jun 2015 06:43:57 EDTnews354260630Discovery of how bacteria survive antibiotics may improve treatment of infectious diseasesInfectious diseases kill more people worldwide than any other single cause, but treatment often fails because a small fraction of bacterial cells can transiently survive antibiotics and recolonize the body. A study published June 4 in Molecular Cell reveals that these so-called persisters form in response to adverse conditions through the action of a molecule called Obg, which plays an important role in all major cellular processes in multiple bacterial species. By revealing a shared genetic mechanism underlying bacterial persistence, the study paves the way for novel diagnostic tools and more effective treatment strategies for a range of bacterial infections.http://phys.org/news/2015-06-discovery-bacteria-survive-antibiotics-treatment.html

The team created thriving strains of genetically engineered yeast using human genes and found that certain groups of genes are surprisingly stable over evolutionary time.http://phys.org/news/2015-05-partly-human-yeast-common-ancestor.html

Recent technological advances, current challenges, and future clinical applications are discussed in the Comprehensive Review article "Advances in Reprogramming-Based Study of Neurologic Disorders" published in Stem Cells and Development.http://phys.org/news/2015-05-techniques-reprogramming-stem-cells-neurological.html
Cell & Microbiology Tue, 19 May 2015 12:38:15 EDTnews351257888Study shows where damaged DNA goes for repairA Tufts University study sheds new light on the process by which DNA repair occurs within the cell. In research published in the May 15 edition of the journal Genes & Development and available May 4 online in advance of print, Tufts University biologist Catherine Freudenreich and her co-authors show that expanded repeats of the CAG/CTG trinucleotide (CAG) in yeast shift to the periphery of the cell nucleus for repair. This shift is important for preventing repeat instability and genetic disease.http://phys.org/news/2015-05-dna.html

And yet, recent research has shown that reality is much more complex: genes can be switched off, or silenced, in response to the environment or other factors, and sometimes these changes can be passed from one generation to the next.http://phys.org/news/2015-02-mechanism-inheritance-advance-evolution-disease.html
